Marc Lobliner is the owner of the popular YouTube fitness channel TigerFitness. He has a large following and thousands of vlog videos. Many beginners follow his advice and training ideas. However, is Marc Lobliner a natural bodybuilder? Can you look like him without taking steroids? The answer inclines strongly towards no because:

1. Gynecomastia

Marc Lobliner has visible gynecomastia (growth of female breasts) in many photos. Having gynecomastia after puberty is often a sign of steroid usage.

2.Insane body transformations

In many before and after photos, Marc Lobliner presents fast and almost unreal body transformations. Natural bodybuilders have a really hard time gaining muscle mass. The process is not fast at all. Yet Marc Lobliner is not a beginner and often gains more than 20lbs during his transformations.

Meanwhile, naturals need years to gain 20lbs of real muscle. Why? Because natural growth is slow, and the potential is lower.

Marc doesn’t claim natty. Calling him a liar is pathetic. He’s an honest and hard working man who doesn’t go out of his way to shit on other people like vegan gains or some other channels do. He makes it very obvious on purpose that he uses steroids (not explicitly) and in no way tries to claim natty.

Sorry to break it to you; but when your using hormones (prescribed or not) you become not natty. You’re altering the level of testosterone your body is naturally producing. Did he claim that he has a legitimate medical issue? Something wrong with his pituitary function? Tumor? You can go to any of these “anti-aging clinics” and get prescribed to testosterone. I along with many friends have done it. It’s just an excuse to pump your testosterone up to the higher end of the “physiological” spectrum. Def on a higher than therapeutic dose during these periods he puts on twenty pounds of lean mass. He is also def on growth. If he says otherwise, he is a liar. I’ve been around for a while, used plenty of anabolics and I can spot a BS artist.

Marc is not natural….not by a long shot. While he does have a script for HRT, it’s just an excuse to not claim natty. He cruises at 500mg/week and will blast to 750 or higher. He’s routinely cycled Tren and uses cutting agents in addition to his strict diet to maintain his condition w/o sacrificing muscle mass. He’s also on at least 2IU of HGH/day. All that and he’s still mediocre. Just goes to show you the genetic limitations of a true natural.

EITHER WAY YOU LOOK AT IT, MARK IS ” ON THE JUICE” I HAVE WON A STATE TITLE AND HAVE TAKEN DRUGS, SO WHEN I SEE MARK, NO WAY IS HE NATURAL!!! INCLINING 315 FOR 8 REPS? COME ON!! NO WAY ANYONE DOES THIS WITHOUT DRUGS!! PERIOD!!! WHAT A JOKE!!!

He says he uses testosterone, and doesnt hide it.
People have this misconception that steroids help you cheat. Yes, they get you there faster, but you still have to work JUST like anyone else.
This man just wants to be happy just like anyone else, so stop judging him about how he lives his life. Jealous? Because people have negative opinions about stuff they feel threatened by….
